and the egg is fertilized with a meat-bearing seed. The pollen/sperm can belong to the original plant or may come from another sunflower. Self-pollination is a mechanism that the sunflower uses to stay alive. On the occasion where the stigma receives no pollen‚ the stigma will twist and wrap itself around its own pollen. Seeds created by self-pollination will only produce flowers that look like the original plant‚ so no hybridization will have occurred.Sunflowers are fast reproducers‚ and one plant

Ventria Bioscience | MGT 493 | Kimberly Stevens | In the 1980s Dr. Raymond Rodriguez‚ a molecular biologist on the faculty of the University of California – Davis‚ and his graduate students embarked on an ambitious research program aimed at improving the productivity of rice. He began to develop techniques to “express” medically useful proteins in rice plants‚ which could be extracted and purified. This technology later became known as “ExpressTec.

Abstract The plant Brassica rapa is a fast plant most commonly known as the field mustard. The plant itself particularly well known for its extremely fast rate of growth‚ making it easy to breed and cross pollinate several generations. Due to its ability of rapid growth it has become a favorite for scientist to test the theories of inheritance on. In our case we tested to see if we could affect the overall hairiness of different generations. F1 seed was ordered‚ germinated and cross-pollinated

We can’t survive without bees Introduction Honeybees‚ which are responsible for pollinating most of the foods we eat‚ like honey‚ oil and fruits. However‚ large amounts of honeybees are disappearing in recent years. According to survey‚ scientists found different viruses in dead bees‚ the guts of bees appeared pathological changes as well. This phenomenon indicates that their immune system once tried to form strong immunity‚ but they failed. From the perspective of spiritual ecology‚ five
